+#### Document Audience Routing (Planet)
+
+In this repository, classify the action's performer before picking a target file:
+
+- Browser/UI end user → `docs/technical/{zh,en}/manual.md` or `quickstart.md`.
+- Shell / Docker / log paths / `planet.sh` / SMTP fallbacks / port forwarding → `docs/technical/{zh,en}/ops-runbook.md` (or an existing `ops-*.md`).
+- Second-party developers → existing `*-context.md` / `backend-*.md` / `earth-*.md` files.
+
+Never put shell commands, log paths, or Docker operations into `manual.md` / `quickstart.md`. Never put UI button labels or screenshots into `ops-*.md`. When the same action has both a UI and a CLI path, write each in its own home and cross-link them with one sentence.
+
 For ambiguous or large documentation changes, briefly state the intended doc plan before editing. For clear small changes, proceed directly.
